Hey guys, maybe you can help me out. I am rendering the inside of a corridor and for lighting I have two long rectangle planes going down the corridor at the wall/ceiling corner, but not touching anything. They seem to be brighter/more burn the farther away from the camera. I'm wanting a nice uniform light all the way down. What am I doing wrong?

Can't say much without taking a look at the model & materials. It looks like you have some highly-reflective walls there; those will be difficult. Also, it looks like this is rendered with the draft engine -- is that correct? This is definitely a situation for the production engine. I would prove the scene first at a much lower resolution, and of course, check that the emitter geometry is not using more triangles than necessary. The lens also looks like it may have a lot of vignetting in this shot -- you might try disabling vignetting and see what effect that has.

Thanks, I'll give those ideas a shot today. It was the production engine, it was really early in the render, maybe that's why it looks like it's the draft.

To disable vignetting, do I enable Devignetting? And what percentage?

yes.
as much as you like. 100% devignetting means no vignetting
(and you don't need to rerender it. just open the mxi and change the vignetting)

new quick render, vignetting off, still getting the falloff in light near the camera.
light source is just a large plane with a skp mat set to the emitter preset. Messed around with multi-light and camera options and still get the falloff in light.

How do they look like if you isolate the emitters and hit render? Maybe they have some kind of mask in the emitter layer.

Hey, sorry I haven't got back to this. Been nusy with other renders.
Anyways, if I isolate everything except for a simply floor plane then it doesn't seem to do the light fall off.

So, not sure what's going on there.
